Summary: | The invention provides an aging performance assessment device for eliminating residual stress of aviation metal parts. The aging performance assessment device comprises a flat plate die (1), a fixed platform (2) and bolts (3), wherein the flat plate die (1) is connected with the fixed platform (2); the flat plate die (1) is used for bearing a test metal part (4) coated with a vacuum bag film (5);a vacuum autoclave (6) is used for carrying out an aging process for eliminating residual stress on the test metal part (4) coated with the vacuum bag film (5) and borne on the flat plate die (1), andpressing the test metal part (4) into a planar plate; and a static test platform is used for carrying out a static or shear assessment test on the plate pressed into the plane to obtain a breaking strength parameter, and confirming the breaking strength parameter of the plate pressed into the plane as the breaking strength parameter of the metal part to be assessed. The device is precise and reliable, and does not damage |
